OBJECT: The students will measure fuel consumption and determine its rate experimentally.

APPARATUS: 1. Internal Combustion Engine 2. Generator3. Calibrated Bar 4. Dashboard 5. Stop watch

THEORY: The Internal combustion Engine takes in Air and Fuel, and burns it to

produce mechanical power. Most of the energy, however, is wasted as heat. That is why engines usually have large radiators. Of the energy present in the combustion chamber (indicated power) only some gets converted to useful output power. The rest is dissipated as friction in the engine, and results in more thermal losses. Here in the present experiment a two stroke engine provides power for producing electricity and heating the surrounding by empowering the thermal heaters.

PROCEDURE:

1. Check the engine before running it, e.g. oil, fuel (Gasoline), water circulation.

2. Turn on the engine to warm it up and then see how the carburetor changes the engine speed and torque.

3. Run the engine in speeds close to 1000 RPM and 1200 RPM, and measure the fuel consumption from the corresponding bar while recording the time, water temperature and torque.

4. Write down your observation within the experiment.5. Determine the input and output powers of the engine. The energy and

mass density of the gasoline used, is 45.7 MJ/Kg, and 719.7 Kg/m3, respectively..
